German supermarket trials charging true climate cost of foods

The Penny chain has raised the prices of products including wiener sausage, cheese and yoghurt

A leading discount supermarket in Germany has raised the prices of a selection of its products to reflect their real cost on people's health and the environment.

In a week-long experiment in all 2,150 branches of the Penny chain, a range of nine products, mainly dairy and meat, will be priced at what experts from two universities have deemed to be their true cost, in relation to their effect on soil, climate, water use and health.
